I.Overview

HZDL-30000A high current generator (referred to as current booster) The high current generator here is a test equipment developed by our company. It integrates the advantages of similar products at home and abroad, adopts numerical control technology, has strong anti-interference ability, and Compared with the previous generation of current boosters, due to the use of low power consumption, large capacity self-coupling voltage regulators and high magnetic permeability iron cores, the converters have the advantages of large output power, small size and light weight. Mainly used for thermal relay, motor protector, contactor, circuit breaker, air switch, switchgear, circuit breaker, protection screen calibration; used for primary busbar protection and the transformation ratio of various current transformers, etc. It is widely used in scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgy and mining enterprises.

II.Main functions

It can output 0～30000A current for a long time

The action time of the test equipment can be synchronized

Automatic identification of normally open and normally closed contacts

Several calibrations can be connected in series at the same time to improve work efficiency

III.Performance characteristics

Using beautiful and elegant PVC panel

Display the test value of primary current and secondary current directly, which is convenient for test observation and record.

High measurement accuracy 0.5 class

High power, small size and strong load capacity

Small size and light weight, the volume is only 30% to 70% of similar products, and it is very convenient to carry.

IV.Operation

（1）After the wiring is completed, check it again to see if there is any wiring error and whether the connectors are in good contact.

（2）During the test, if there is any abnormal phenomenon such as ignition and no display when starting up, immediately turn off the power and recheck the wiring.

（3）During the actual wiring, the current output terminal should form a loop, otherwise the instrument will not output current.

（4）The current riser has random output wires; the output external copper wires are selected according to 10A/mm2. (The standard configuration is two 1-meter test leads)

（5）The capacity of the equipment is designed for short-time work of 5 minutes.
